Hello,
this might either be a problem with the value of 'tllogic' in your code or a bug in the C# client (which is not directly supported by the core development team).
The following python client code works fine on your networks and returns '3' for each of your defined tlLogics.
for tlID in traci.trafficlight.getIDList():
print(tlID, len(traci.trafficlight.getControlledLinks(tlID)))
Note, that your networks are highly unusual and will not correctly model common vehicle interactions. In your network, cars will pass through each other if they happen to be on the intersection at the same time.
Instead of modelling the connections across a junction as "normal" edges, they should be modeled as "connections" that are all part of the same junction.
Also, parallel lanes of the same road should be modeled as lanes of the same edge since otherwise, lane-changing will not be possible.
regards,
Jakob
